Average, Median, Sobel, and Edge Filters were applied to the
image sequentially. The Average filter applied to the RADARSAT-1
Standard-2 beam mode, showed a global mean value of 92.12.
The median value was 83 while the standard deviation value was
51.97. The mean value of the Average filter did not change from the
mean of the original image at 92.12. The Average filter helped to
remove some speckle from the image although the land area still
needed some filtering to be clear.
